- W2500979880 abstract "The properties of solid oxide fuel cell (SOFC) cathodes consisting of (La,Sr)(Fe,Co)O3−δ-type (LSFC) perovskites were examined. For this purpose, anode-supported single cells with yttria-stabilised zirconia (8YSZ) electrolytes were used. On the electrolyte, a Ce0.8Gd0.2O2−δ(CGO) interlayer and the LSFC cathode were screen-printed. Emphasis was placed on the effect of changing material properties and processing parameters; i.e. the influence of sintering temperature of the CGO interlayer and composition of the LSFC cathode. It was found that the performance was best for sintering temperatures of the CGO interlayer of at least 1300°C. A La0.58Sr0.4Fe0.8Co0.2O3−δ cathode, together with a CGO interlayer, considerably improved the overall power densities (0.77 W/cm2 at 750°C) compared to SOFC with a La0.65Sr0.3MnO3-δ/8YSZ composite cathode (0.39 W/cm2). This was particularly the case for operating temperatures between 650 and 750°C. Regarding a La0.8Sr0.2Fe0.8Co0.2O3−δ cathode, the higher lanthanum content resulted in lower electrochemical performance." @default.
